"The door to our unit stuck every time we tried opening it. The room smelled musty. We had a kitchenette but no cleaning products so we couldn't even wash the coffee cups we used. We had one bar of soap in the bathroom that was about 1/2 inch in size for the five days we were there. I had to transport it from the bathroom to the kitchen as needed. No toiletries provided so we had to make our own last. The only lighting was in the kitchen, bathroom, and two wall lights over the bed which made time spent in the living area extremely dark. There was no remote for the TV. I asked the desk attendant if we could have one and his response was, "Do you need one?" One was given to us. By our third day, we had used the three coffee pods provided and I asked the desk attendant if we could have a few more. She asked if we wanted regular or decafe and I said regular. She couldn't muster up any and said she'd have some dropped off at our room. Three hours later, a guy brought two decafe packages! We are not that picky, just loooking for a clean room with minimal amenities. We will not be staying there again."

"Very nice hotel for a quick stay. Super friendly and helpful staff. Seriously well kept property. The room was large and comfortable with plenty of room and storage. Everything was in it's place and we didn't have to look or call for anything extra. The bed was really comfortable and had to wake up early the next day and really didn't want to. Will definitely stay here again! PS. The breakfast was perfect. The coffee was really good. And the lady at the check-out was super, super nice!"

"Staff smelled like marijuana, my reservation was not held and they have to place us in another room. They handed sheets and blankets for Sofa bed at check in. Once we arrived at our floor (2nd floor) it smelled like wet dirty carpet. You can see stains in the hallway carpet. When we entered our room we right away noticed a very filthy carpet, dirty walls stains on sheets, bath tub dirty and moldy and there was a missing drawer knob with zip tie and a hole punched into the restroom door. The window did not have a screen on it and it opened wide enough for our 4 child fit through. The coffee table was dirty and stained and we had to ask for extra blankets for our 4 yr old to play in the dirty carpet. The toilet was overflowing and it took 4 phone calls and 1 1/2 hr for staff to come fix. Front desk phone is always busy and so we had to call the hotels public phone number just to reach them. The breakfast buffet was unpleasant. Tater tots were gray on the inside and oatmeal was slimy. When we asked for 3 towels for the pool they could only find 2, which were old and small. The pool area is very rundown. Cracks in cement that could easily cause injury. Chairs and tables seem to not have been clean in months. We are usually happy with hotel stays and are never really critical of our stays, but at this point we would have rather loved to stay at a Motel 6. I would not recommend this Hotel to anyone. Please pay attention to the pictures on the website as they can be deceiving."
